United States Patent ice 3,498,300 SLEEVE TYPE HAIR CURLER Bernard J.Lehn, T. L. Cantley, 7635 Ben Ave., North Hollywood, Calif. 91605 FiledSept. 7, 1967, Ser. No. 666,119 Int. Cl. A45d 2/00 U.S. Cl. 132-40 1Claim ABSTRACT OF THE DISCLOSURE The device is a two piece hair curlerof the type having a spring clip for holding the hair to the curler. Theimprovement resides in the configuration of the clip which is a U-shapedmember normally having one leg on the inside and one on the outside ofthe curler. The inner leg is conigurated to have bends in it to providea part of substantial extent that lies juxtaposed against the insidesurface of the inner member of the curler, the configuration of the clipbeing such that in the unstressed condition the said part of the innerleg of the clip lies against and parallel to the outer leg.

Basically, the use of hair curlers is conventional and well known. Inthe type of hair curler concerned with herein, the hair is clipped orsecured to a cylinder or mandrel by means of a spring clamp or cliphaving the shape of a bobby pin. The spring clip is carried by a secondsleeve or cylinder which is insertable into and retractable from the rstcylinder. To appreciate the nature of the improvements of the invention,the technique of use of this type of hair curler should be understood.The spring clip is generally of U-shape and normally with the innersleeve inserted into the outer sleeve, one leg of the clip is on theoutside of the outer sleeve and the other leg is on the inside of theinner sleeve. In the technique of use, with the parts of the curler inthis position, strands or tresses of hair are wound around the curler onthe outside of the outer leg of the spring clip. (More than one springclip can be used if desired.) The hair is wound around the curler untilthe curler is down to the scalp. The inner sleeve is then withdrawn,drawing the outer leg of the spring clip out from underneath the hair.The inner sleeve is then rotated until the spring clip is next adjacentto the scalp in which position, the spring clip, having a particularshape as will be described hereinafter, the outer leg tends to moveoutwardly away from the curler so that when the inner sleeve and thespring clip with it are now inserted into the outer sleeve, in thisposition, the outer leg of the spring clip engages hair between itselfand the outer sleeve. When the inner sleeve reaches its inner positionthe action of the spring clip deriving from its particular shape causesthe outer leg to move toward and adjacent the outer cylinder so as toclip or clamp the hair between itself and the outer sleeve of thecurler. One of the principal objects of the invention is to provide aconfiguration of spring clip or clamp such that the result justdescribed can be realized as will be described in greater detailhereinafter.

Another object is to provide a hair curler as described wherein thespring clip is generally of U-shape, the inner leg having a bendrelatively close to the yoke of the spring clip with an intermediateportion normally lying parallel to and closely adjacent to the outerleg. This shape makes possible results as described above.

Another object is to provide a hair curler as described wherein theSleeves are made of a moldable material, such as plastic, havingembedded therein metal particles such that the sleeves have attractionfor the hair which becomes negatively charged while curling so that thehair clings to the curler as desired, and so that the particles PatentedMar. 3, 1970 in the sleeves can retain heat and thereby promote dryingof the hair.

Another object is to provide a hair curler as in the foregoing whereinthe utilization is improved by providing one or more axial grooves onthe inside of the inner cylinder to guide the inner leg of the springclip, or clips.

Another object is to provide a hair curler as described wherein theinner and outer sleeves are provided with apertures which are inalignment transversely as respects the sleeve to allow straight throughor transverse ow of circulating air.

Further objects and additional advantages of the inyention will `becomeapparent from the following detailed description and annexed drawingswherein:

FIGURE 1 is a side view of a preferred form of the invention with theinner sleeve retracted;

FIGURE 2 is a view similar to that of FIGURE l with the inner sleevepartially inserted;

FIGURE 3 is an enlarged sectional view of the curler with the innersleeve inserted;

FIGURE 4 is a sectionalview transverse to the axis of the curler;

FIGURE 5 is a partial sectional view like that of FIG- URE 3 with theinner sleeve in partly retracted (or nserted) position;

FIGURE 6 is a View of the preferred form of spring clip used;

FIGURE 7 is a partial sectional view of a curler wherein the sleeveshave metal chips embedded therein.

Referring to FIGURES 1 to 6, numeral 10 designates the outer sleeve,numeral 12 the inner sleeve, and 14 designates the spring clip or pin ofthe curler. The sleeve 10 is cylindrical and may be made of suitablematerial, preferably plastic. At one end there are external knurls 16which facilitate grasping the curler for rotating it as will lbedescribed. At its other end, the sleeve 10 has an internal end rib orflange 11. 'I'he sleeve 10 has apertures in it as designated at 20 whichare preferably arranged so that apertures in opposite sides aretransversely aligned to facilitate circulation of air laterally throughthe curler. See FIGURE 4.

The sleeve 12 is of similar construction, preferably being made of lightweight material such as plastic. Its diameter is slightly less than thatof the sleeve 10 as may be seen in FIGURE 3. At its inner end there isprovided an external rib 24 which is able to engage against rib 18 onthe inside of the sleeve 10, these parts preventing the inner sleevefrom being entirely withdrawn. At the left end of the sleeve 10 are twoexternal knurled ribs 30 and 32 slightly spaced from each other, theseribs providing a grip to facilitate holding the curler when being usedas will be described. Between these ribs at one point in thecircumference there is provided an aperture designated at 34. The springclip is held in this aperture. The spring clip 14 Iresembles a bobbypin. It is a U-shaped spring member having an outer leg 36 and inner leg38 extending from the yoke or U-bend part 40. Preferably the ends of thelegs are encased in hardened plastic 42 and 44 which forms a smooth beador bulb on the ends of these legs to prevent injury to the scalp orfingers in use. The inner leg 38 has a bend in it as designated at 46spaced from the U-bend 40 so that in the unflexed condition of thespring clip it has an intermediate portion which lies parallel to andjuxtaposed against the other leg 36. (See FIG. 6.) At the end of the leg38, it has an inwardly bent part 52 so that normally the ends of the twolegs are spaced from each other to provide for easily insertingsomething between them and opening the clip.

FIGURE 6 shows a preferred form of clip or holding pin. Theconfiguration can be varied in having bend 46 spaced farther from theU-bend, the shape otherwise being the same or substantially the same.

On the inside of sleeve 12 as shown in FIGURE 4, there is a guidewayprovided by two closely spaced axial ribs 54 and 56, the aperture 34being a position between these ribs at the left end of the sleeve 12.The clip 14 is in a position as shown with its U-bend 40 in the aperture34 with one leg on the outside of the sleeves and the other leg on theinside. The sleeves 10 and 12 are formed or fabricated preferably tohave metal chips such as aluminum chips as designated at 60 and 62 inFIGURE 7 molded therein. The purpose of these chips isthat is has beenfound that when the curler is in nse the hair becomes positively chargedelectrically and is attracted by the metallic chips embodied in thesleeves. Further these metal chips retain heat and facilitate the dryingof the hair when the curlers are in position. The curler can of coursebe made without embedding metals chips.

Referring to FIGURE 4, additional axial ribs 62-68 are provided on theinside of sleeve 12 to provide guideways for additional spring clips,apertures being provided for these clips similar to the aperture 34. Asingle spring clip may be used with the curler or optionally more thanone may be used.

The technique of use of the curler is as follows. The primary purpose ofthe inner sleeve is that of holding the spring clip and facilitating itsmanipulation. In use, the inner sleeve is inserted into the outersleeve. With the curler in position spaced from the scalp or head,tresses of hair are then rolled or wrapped around the curler by rotatingit, the hair wrapping around the outside of the' outer leg 36 of thespring clip 14. When the curler has been rotated or rolled down to thescalp, the inner sleeve 12 is then retracted, that is, pulled out and itis then rotated relatively to the outer sleeve 10 to bring the springclip 14 into position next to the scalp. The'inner sleeve is nowinserted into the outer sleeve, the outer leg 36 of the spring clipclasping the tresses of hair that are between the scalp and the curler.The clip 14 is particularly congurated to facilitate this purpose. Asthe inner sleeve is inserted the outer leg 36 of the spring clip 14 rsttakes the position as shown in FIGURE wherein the action tends to spreadthe legs of the spring clip in the manner shown. This facilitates theengaging and clasping of the hair between the outer leg of the springclip and the curler. As the inner sleeve moves from the position ofFIGURE 5 to the fully inward position of FIGURE 3, the outer leg movesinwardly towards the curler with a snap action, clasping the hair asshown in FIGURE 3,

this snap movement being accompanied by an outward snap movement of theU-bend 40 of the clip in the aperture 34. The curler is now in position.

From the foregoing those skilled in the art will readily understand thenature and utility of the invention and the manner in which it achievesand realizes the objects and advantages as set forth in the foregoing.
